Product Details

Quad Axle Bitumen Tank Semi Trailer / Hot Asphalt Transport Semi Trailer

Our quad axle bitumen tank semi-trailer is specially designed for long-distance transportation of hot liquid bitumen and modified asphalt, widely used in asphalt refineries, mixing plants and highway infrastructure engineering.

The tank body adopts high-strength Q235B carbon steel, equipped with multi-layer rock wool thermal insulation and built-in thermal oil heating coils. The diesel burner heating system keeps the asphalt fluid and effectively prevents bitumen solidification during transportation. Built-in anti-wave baffles reduce liquid sloshing to improve driving safety.

Product Data
